Solis-Cohen and Weiss1 proposed the term "Laurence-Moon-Biedl syndrome" in 1924 when they summarized the reported cases. Since Bardet2 added polydactylism as one of the criteria for diagnosis, some authors prefer the term Laurence-Moon-Bardet syndrome. Reilly and Lisser,3 in 1932, reviewed 77 cases.
